Abstract

A laser localizer may include a laser pointer on handle to be placed co-parallel against the surface of a detector head of a gamma camera and a mirror angled to direct the laser beam normal with respect to the detector head surface. The source of radiation may be a button containing Co-57 or other radioactive material placed under the mirror. When the image of the radioactive material in the laser localizer is superimposed on an image of a source of radioactive uptake in the patient on a system monitor, the laser beam will automatically point to the source within the body.
